The musical notes in these songbooks are colour-coded to match the tubes according to Boomwhackers' Chroma-Notes™ Coloured Music System. The coloured notes enable anyone to easily play and learn about reading music at the same time. One person can play the songs on a XyloTote Tube Holder or several people can each have one or two tubes and play their notes as needed - a great group activity! This volume has 22 familiar songs and uses the C Major Diatonic Tubes and the Chromatics Set. Uses four different set-ups of tubes in the XyloTote™ for playing songs in various keys.
